Solar systems for camper, caravan and campingIndependence from the usually high electricity prices on campsites offers a self-sufficient power supply. This can be ensured in a motorhome, caravan and camper with the help of a photovoltaic system.
A solar system is certainly one of the most sensible purchases around the motorhome. As a rule, solar systems can be installed relatively easily and connected to the existing on-board battery. The installation on the roof of the caravan, camping car or motorhome is usually under ventilated. This is to prevent heating of the modules.
Different cell technologies
There are two interesting options for motorhomes for solar modules: with amorphous and crystalline cell technology. The advantage of amorphous cells is their flexible application, which is possible even on uneven substrates. However, a disadvantage of this technology is the lower efficiency. The highest efficiency is achieved by monocrystalline cells. Although CIS solar modules have a slightly lower efficiency, they can convince by their insensitivity to partial shading. Because at the campsite a shadow can not always be completely avoided by satellite antennas or branches.
principle of operation
A solar system basically consists of one or more solar modules, which are composed of individual solar cells, and a controller. The light radiation converts the solar cells into electrical current, which is delivered to the on-board battery. The respective state of charge of the battery is detected by the controller. This ensures that the battery is always in
optimal state of charge is located. An upgrade of the on-board electronics is not required because all consumers can remain connected to the battery as before.
Plant dependent on the power requirement
The size of the solar system must take into account the amount of daily energy required for the refrigerator, stove, pump, lighting, satellite / TV, etc. For smaller touring vehicles without Sat / TV, a solar system with 60 watts may be sufficient. A solar system with 80/85 watts can provide the necessary energy for small to medium sized touring vehicles during the travel season from spring to autumn. Medium to large touring vehicles should be equipped for the same travel time with a solar system from 100 watts. However, if motorhomes of this size are used throughout the year, a solar system from 160 watts makes sense. Also around the year can be used large mobile homes with a solar system from a wattage of 240 independently. For the year-round use of course, a corresponding insulation of the mobile home is required, so that the power consumption is not unnecessarily increased.
No matter whether lead-acid batteries for stationary operation or gel batteries for mobile operation, solar batteries were specially adapted to the requirements of solar power technology. In addition, they impress with their high charging efficiency. They have only a low self-discharge and are usually durable in cycle mode.
Consultation and installation by a specialist
For the selection as well as for the adjustment of the individual components one should consult a specialist. The installation should also be carried out by a specialist company. The German Solar Industry Association (e.V.) offers its contacts to specialist companies on its association's homepage at solarwirtschaft.de/verbraucher/handwerkerkontakt.html
